The Royal Family has taken to social media to publicise an upcoming ITV documentary centred on King Charles's formative Arctic expedition from five decades ago.
Steve Backshall's Royal Arctic Challenge will see the renowned environmentalist follow in the monarch's footsteps through Canada's frozen north.
The programme is scheduled to broadcast tomorrow evening at 8.30pm on ITV and ITVX.
Backshall's journey examines how climate change has transformed the region in the half-century since the then-Prince of Wales undertook his groundbreaking visit to the area in 1975.

During his 1975 expedition, the young prince undertook a historic dive beneath the Arctic ice, braving the extreme cold of Canada's northern waters.
The visit proved to be a genuine adventure that saw him experience dog sledding across the frozen landscape whilst immersing himself in indigenous culture.
This transformative journey played a crucial role in cultivating the King's enduring commitment to environmental causes.
Backshall's documentary will assess the ecological changes that have occurred across the Arctic over the past fifty years, highlighting the effects of rising global temperatures on this remote wilderness that so profoundly influenced the King's outlook.
The TV appearance on Thursday comes just days after King Charles delivered a historic televised message as part of Channel 4's Stand Up To Cancer 2025 broadcast, sharing positive news about his ongoing battle with the disease.
The 77-year-old monarch announced that his cancer treatment schedule will be scaled back in the New Year, describing the development as "both a personal blessing and a testimony to the remarkable advances that have been made in cancer care in recent years."
The address, which aired at 8pm on Friday night, represented an extraordinary departure from royal convention regarding the sovereign's private medical matters. It was recorded in late November at Clarence House's Morning Room.
The King used the platform to urge viewers across the United Kingdom to prioritise cancer screenings, revealing that a minimum of nine million people have fallen behind on available screening programmes.

The monarch first learned of his condition in February 2024, when medical professionals identified a form of cancer during a hospital procedure for an enlarged prostate. Buckingham Palace confirmed the illness was unrelated to prostate cancer but has not disclosed the specific type, citing the King's right to medical privacy.
Since receiving his diagnosis, the King has attended weekly treatment sessions whilst maintaining a demanding schedule of official engagements. His working calendar has remained full throughout the past year, including five state visits completed in 2025.
The decision to speak openly about his health marks a significant shift in how the Palace approaches communication about the sovereign's wellbeing.
When initially announcing the diagnosis, the Palace explained that the King wished to share his condition publicly to avoid speculation and help others affected by cancer worldwide.
